The Three-Phase Four-Wire Cabinet-Type Active Harmonic Filter (APF) offers a robust solution for harmonic mitigation in four-wire power systems. Utilising DSP+CPLD digital control and a three-level topology, this APF delivers precise harmonic compensation up to the 50th harmonic, addressing three-phase imbalances and neutral line harmonics. The modular design allows for scalable capacity through parallel connection. Housed in a robust cabinet with independent air ducts, the Three-Phase Four-Wire Cabinet-Type Active Harmonic Filter ensures reliable operation in demanding environments. Available in a range of voltage and current ratings, this APF provides comprehensive power quality improvement.

Model description:

Features:

● Use DSP+CPLD all digital control core, three-level topology technology, advanced harmonic detection algorithm and PWM control strategy to achieve accurate compensation of harmonic current.
● Adopt modular design, which facilitates parallel connection of multiple modules, takes up little space and is easy to maintain.
● The structural design of independent air ducts and independent warehouses ensures the stable operation of the equipment.
● It can filter harmonics in a wide range of harmonics, from 2 to 50 harmonics, and solve the problem of three-phase unbalance at the same time.
● The harmonic filtering rate is high. If the capacity allows, the harmonic current filtering rate can be as high as 95%. Set 100% current limiting output to ensure long-term stable operation of the equipment.
